Thank you for clarifying. So far the target for this project is desktop browser and tablet browser (like iPad); so I am not using JQM.

>I didn't mean mobile web site I meant using the "jquery mobile" framework. The JQM framework uses ajax almost exclusively for navigation and for each page navigated to, the html is injected in a designated div thus none of the header code that is normally associated with a web page will be rendered. For example, anything withing the head tags will be stripped out so will never run so "ready" will never run. There are numerous events programmed into the framework to allow for manipulation as the ajax loads such as pageinit, pagebeforeshow.... These events are all hooked up using on or delegate events so they are active event if the page has in not completely loaded.

>>I didn't realize that ready() should not be used in Mobile applications. Can I ask you why? Does it mean that when you run a page on iPhone browser the Ready() will not work?
>>I don't use Ajax yet at all. So at this point the "replacing the button using code snippets" goes over my head; unfortunately.
>>Thank you for your input.

>>>Not to confuse you, there are other options using Jquery. This binds the click event to your button ready to use even if the button had not been created in the dom yet. I give this example in case you ever get into Jquery Mobile because use ready() is a big no no. Also, if you are using a lot of Ajax and replacing the button using code snippets, the click event using bind will be lost but using on the click event says in tact.

>>>>Does method FireClickMethod fire when user clicks on any of the buttons? Of course I understand that jQuery will look for element ‘btnTest’ and will determine if the click was on this button. But I just wanted to understand that method files FireClickMethod() on every click or other event on the page. Do I understand this correctly?
